I have the javelin ,rugged ridge, Harris and the mod Evolution. and have used a hatch. I prefer the javelin for my light rifles. its quick to deploy easy to leave in pocket and light. the mount is small and barely noticeable. but I wouldn't leave it on to pack around. I dont trust the magnets that much. the harris was my first bipod and liked it but believe a lot of these others are a bit better in multiple ways(weight,versatility,bulk,noisy). if I wanted it to be a sitting type bipod I would get the hatch or Rugged ridge with extensions. the evo offers extensions but have not used them yet. my evo is new to me and haven't used it yet. it feels solid and tight. Broz talks highly of this bipod. my rugged ridge is very solid, quiet fairly compact and offers extensions. for my heavier rifles it's been my choice.
